APPARATUS FOR- RAISING AND MOVING MATERIAL.

SPECIFICATION forming part .of Letters PatentNo. 466,601, dated January 5, 1892.

, Application filed July 13, 1891.

To all whom it may concern:

Be it known that I, JOSEPH N. DREW, a citizen of the United States, residing at Malden, in the county of Middlesex andState of Massachusetts, have invented certain new and useful Improvements in Apparatus for Raising and Moving Material, of which the following, taken in connection with the accompanying drawings, is a specification. 1o- My invention relates to that class of appa-' ratus employed for raising and moving materials from place to place; and the invention consists in certain details of construction, as hereinafter fully described, and pointed "out in the claims.

Referring to the accompanying drawings, Figure 1 represents a side elevation of an apparatus for raising and moving materials embodying my invention. Fig. 2 is a side view of a portion of the track and one of the carriers drawn to a larger scale. Fig. 3 is a plan or top view of thesame. Fig. 4 is a vertical section taken on line w as of Fig. 2. Fig. 5 is aside View of one of the supporting-plates be- 2 5 fore it is bentinto form. Fig.- Gisa plan view of same after itis bent. Fig. G isa sideview of the other support-ing-plate.' Fig. 7 shows a modified arrangement for supporting the track. Fig. 8 is a vertical section taken on 0 line y y of Fig. 7.' Fig. 9 is a similar section taken on line .2 .2 of Fig. 7. Fig. 10 is a side view.of a portionof the track and counterbutter. Fig. 11 is a sectional view of the same. Figs. 12 to 11L show a modified means for sup- 3 5 porting the channel-irons from the cross beams, Fig. 12'being a side view. Fig. 13 is a vertical section taken on line 1) o of Fig. 12, and Fig. 14 a vertical section taken on line 10 w of Fig. 12. 0 The frame-work of the apparatus. may be constructed in any suitable manner. In the drawings I have show it consisting of standards A A,'provided :1. their lower ends with small wheels 13 B, that run upon a track 0. The standards are connected together at their lower ends by stringers D D.

Upon the top of each of the standards A are secured cross-beams E. To the crossbeams E are secured hangers F, that carry the track. These hangers each consist of two Serial No- 399,267. (No model.)

flat plates of metal G G out to the form shown in Figs. 5 and 6-, and placed. side by side. The inner ends Z Z of plate G are bent over, as shown in Fig. 6, so as to embrace the flattened ends of bolts g. The plates G G and bolts are all secured together by rivets h. If desired, only one plate G may be employed; butI prefer to use two, so as to give additional strength and flexibility. A flat plate H is placed over the top of each of the cross-beams 62: E, through which plate the bolts 9 pass and are secured by nuts g. On each'side of the lower portion of the hangers F are secured channel-"iron beams Ibymeans of bolts J. The lower flanges oithese'channel-iron beams 65 form the tracks upon which travelers K run. I The frame of the travelers K maybe of any desired form ofconstruction,according to the material it is desired to raise and move.

The axles 70, upon which the. running-wheels 7 o L are mounted, are set on an angle equal to the angle of the lower flange of the channel- 'iron beams I, so that the wheelswill have a full bearingrsurface, and just opposite the edge of said flanges the travelers are provided with anti-friction rollers M, (see Fig. 4,) so 7 that should they at any time come into' contact with the flange, as in going round a curve, there will not beany friction to retard the speed.

The travelers K are connected together by means of rods or tension members N, secured to a bar n on each of the traveler frames, so as to forma train of travelers that are moved in one direction by a rope or cable P and in the opposite direction by a rope or cableQ, (see Fig. 1,) both'of which are operated by any suitable mechanism. The bar of the last traveler at its ,rear end isformed with a slot to receive a bar 91, (see Figs. 1, 10, and 11,) so that when the trainhas reached the end of its journey the bar at will come into contact with a counter-butter and be stopped at the required place, as hereinafter described.

At suitableintervals to the top of the chan- 5 nel-iron beams I are secured metal frames R, (see Figs. 1, 10, and 11,) to each of which is secured a counter-buffer S by means of a bolt 3, upon which it is freeto turn. Thelower end of the countenbufter S. works between me of travelers is free to pass; but when lowered,

as shown in full lines, the bar it at the end of the last traveler will come in contact therewith and the train be stopped.

In the connections between the stringersl) and standards A and also between the channel-iron beams I and 'the hangers F a small amount of slackness or play is allowed, so that the whole construction will adapt itself to the required position when passing round In Figs. 7, 8, and 9 I have shown a moditied form of the hangers for carrying the channel-iron beams or tracks. G is a short piece of metal of I form having projecting ends 9 This pieceof metal is secured to the beam E by means of bolts 9 passing through a plate 11, arranged on the topof the. beam E, where they are secured by nuts 9". The endsof the channel-iron beams I are inserted between the proiecting ends 9 of the hangers GLand are retained in place at their upper ends by cutters and pins 3' and at their lower ends by countersunk headed bolts j; (See Fig. 9.) r

In 12 to 141 have shown another modification of the means for supporting the chaunel-iron beams I from the cross-beams E. In this case each pair of the channel-iron beams I is rigidly connected together, plates. beinginterposed between them at suitah e intervals to keep them the proper distance apart,

the beams and plates'being secured together by rivets q, and near the ends of'the beams I are secured bolts or rivets r. g are bolts the lowerbndsof which are flattened and bent into-the form of a book, as shown in dotted lines in Fig. 12. These hooks are .passed underthe bolts or rivets r, and apiate s of about the formshown-is placed between the beams I and to the rear of hooks, the plate being held in place by bolts or rivets 1" passing under the same. The upper ends of the bolts g pass through the plate II, and are secured by nuts, as before described.

What I claim as my invention. isa 1. In an apparatus for raising and moving material, a track consisting of two channeliron beams supported at suitable intervals'by hangers secured between said channel-iron oi July, A. D. 1891.

beams and carried by cross-beams, whereby the lower flanges of said channel-iron. beams form the track for the travelers to run upon, substantially as set forth.

2. In an apparatus for raising and movingmaterial, a track consisting of two channeliron beams supported from overhead crossbeams carried by suitable frame-work, in combination with a train of carriers suspended from and adapted to travel upon the ,lower flanges of said channel-iron beams, substantially as set forth.

4. In an apparatus for raising and moving material, the combination of a track consisting of two channel-iron beams supported at intervals by hangers secured to cross-beams on a movable frame with a train of travelers adapted to run upon the lower flanges of said channel-iron beams and having running and anti-friction wheels, said travelers being connected one to another by a rod or tension membergall arranged as set forth. a

5. In an apparatus for raising and moving material, the counter-buffer S, in combination with a track consisting of two channel-iron beams, said bufier being mounted in a metal frame secured on the top of said track, substantially as set forth.
